The Lowdown
G’day, it’s Rusty.
Alright, we’ve got a solid stretch ahead at Jaconé, but you’ll want to pick your moments. Monday’s a no-go with light rain and messy cross-onshore wind – just leave it. Things start to fire up from Tuesday afternoon.
That Tuesday arvo is one to highlight. We’re looking at 10 ft of south swell with a 13-second period, packing moderate to strong energy. Wind goes light cross-offshore, leaving the surf clean. But 10 ft is serious size – this is strictly for experienced surfers only. Beginners, give this one a wide berth.
Then Wednesday and Thursday mornings are absolute crackers. Wednesday dawns with offshore winds from the ENE at 15 km/h, grooming a 7 ft south swell – again, expert territory, but the conditions are excellent. Water temp is around 74°, a touch warmer than normal for August, which is a bonus at Jaconé (Rio de Janeiro). Thursday keeps the good run going with clear skies, light offshore NE wind, and a 7 ft south swell – clean and punchy. Crowds can show up sometimes, but with quality like this, it’s worth sharing.
Friday and Saturday ease off a bit in size but stay clean and lined up. Saturday morning is a beauty – 6 ft from the south, ENE offshore at 15 km/h, all glassy.
Into the second week, we see a drop from Sunday onward. Sunday and Monday come in around 4 ft down to 3 ft, still clean with light winds – more of a longboard or funboard kind of vibe.
Tuesday the 18th is flat and lumpy; skip it. Then we get another pulse. Wednesday the 19th afternoon sees a new SSW swell of 8 ft pushing in, and by Thursday and Friday mornings we’re back in business. Friday the 21st morning is a standout: 8 ft from the SSE with a long 14-second period, light offshore NE wind, and excellent conditions for experienced surfers. That swell direction suits Jaconé’s exposure nicely. Energy is strong. Just note – long period groundswell like that can make beach breaks a bit straight, but here it should still hold shape.
The final days fade out again with small waves under 3 ft from the 23rd onward. Pretty ordinary, but forecasts can always turn.
Best bets: Tuesday arvo and the Wednesday/Thursday mornings of the first week, plus Friday the 21st. A proper run for the experienced crew.
Rusty, out.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
